Memtest86, the best memory detection software in Linux

Memtest86, the best Linux memory detection software, is a general Linux technology-Linux programming and kernel information. For details, see the following. Memtest86 is a free memory testing software with a high test accuracy and the potential memory problems can also be checked out! You can download the latest release on the http://www.memtest86.com/page.

Memtest86 is a Linux-based testing program. Therefore, it is installed and used differently from other memory testing software. After downloading the memtest86program, we can see 4 files in which install.exe is used to install the Memtest86 program to a floppy disk. Double-click to run the program. In the pop-up window, Enter "Enter Target diskette drive:", Enter the drive letter of your floppy disk drive, for example, a, and press Enter. Insert a formatted floppy disk and press enter to start installation. Then, Memtest86 is installed on the floppy disk. We mentioned earlier that Memtest86 is based on the Linux core, so we cannot see the content on the floppy disk in Windows Resource Manager (do not mistakenly think that there is no content in the floppy disk ). If there is no soft drive, the Memtest86 home page has the ISO file of the software, you can directly burn to the CD, start with the optical drive for testing.

Test memory

After a floppy disk is created, we use this disk to start the computer Memtest86 to automatically test the memory, as shown in interface 1. Under the "Memtest-86 v3.0" program version displayed in red, we can see the processor model and frequency used by the current system, as well as the size and speed of the CPU level-1 cache and level-2 cache, of course, it also includes the capacity and speed of the system physical memory, the main character of the test. The last display is the chipset type used by the motherboard. Through this information, we can have a general understanding of the main configurations of the system.

The Test Progress is displayed on the right of the system information, "Pass" shows the completion progress of the main Test process, and "Test" shows the completion progress of the current Test project. "Test #1" shows the current Test project.

The "WallTime" below shows the time consumed by the test. In this row of data, the "ECC" column shows whether the current memory supports enabling the ECC verification function, "TEST" shows the TEST mode, which is available in "standard" and "full" modes. "Pass" indicates the number of times the memory test has been completed. The Memtest86 test has unlimited loops. It will continue testing unless you end the test program. In addition, the test of Memtest86 is time-consuming. It takes about an hour to run the test in the standard mode. If it is a full test, it takes several hours (related to the memory capacity ).

Perform a full test

Click the "C" key to open the settings menu of Memtest86, and then click the number key "2" and select the "Test Selection" option (Note that the number is entered from the primary keyboard ), click "3" and select "All Test" to enable the full Test mode. With this menu, we can also perform more settings, such as setting the Cache size for the test and restarting the test.

After the test starts, major memory emergency problems (such as "death" bits) will be detected within several seconds. If the fault is triggered by the special location mode, it takes a long time for the test to be detected. When Memtest86 detects a defect, an error message is displayed at the bottom of the screen, but the test continues. If there is no error message after testing several times, we can determine that the memory is stable and reliable. If a problem occurs during the detection, you can try to reduce the option value of the memory parameter in the BIOS, such as setting the memory CAS delay time to 3 and then testing. This may avoid errors, ensure the stability of the memory runtime.

Finally, it is worth noting that if your system has multiple memory records (I believe there are a few in your machine), you need to test each memory separately, in this way, we can identify the memory error. In fact, the Memtest86 test memory is not only limited to the test memory quality, but also can be used to test the memory and system stability several times in its full test mode. Therefore, if your system frequently encounters the problems described at the beginning of this article, you may want to test your memory with Memtest86.
